Marketocracy.com lets you create a portfolio of stocks and trade and track them. Joy has read the two books Bob wrote on investment software and advice but didn’t really get into it until she bought some virtual stocks through this web site. (She’s up 5 percent in the first week.) You can invest up to $1 million of virtual money. If you create a dud portfolio, dump it and start over. (Some brokerage firms also allow you to create test portfolios and track them, by the way.)
